    Sequence-directed DNA translocation by purified FtsK (2005)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2005-02-01
    Description: DNA translocases are molecular motors that move rapidly along DNA using adenosine triphosphate as the source of energy. We directly observed the movement of purified FtsK, an Escherichia coli translocase, on single DNA molecules. The protein moves at 5 kilobases per second and against forces up to 60 piconewtons, and locally reverses direction without dissociation. On three natural substrates, independent of its initial binding position, FtsK efficiently translocates over long distances to the terminal region of the E. coli chromosome, as it does in vivo. Our results imply that FtsK is a bidirectional motor that changes direction in response to short, asymmetric directing DNA sequences.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Pease, Paul J -- Levy, Oren -- Cost, Gregory J -- Gore, Jeff -- Ptacin, Jerod L -- Sherratt, David -- Bustamante, Carlos -- Cozzarelli, Nicholas R -- GM07232-27/GM/NIGMS NIH HHS/ -- GM08295-15/GM/NIGMS NIH HHS/ -- GM31657/GM/NIGMS NIH HHS/ -- GM32543/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 2005 Jan 28;307(5709):586-90.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Molecular and Cell Biology, University of California, Berkeley, CA 94720-3204, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/15681387" target="_blank"〉PubMed〈/a〉

    Light-responsive cryptochromes from a simple multicellular animal, the coral Acropora millepora (2007)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2007-10-20
    Description: Hundreds of species of reef-building corals spawn synchronously over a few nights each year, and moonlight regulates this spawning event. However, the molecular elements underpinning the detection of moonlight remain unknown. Here we report the presence of an ancient family of blue-light-sensing photoreceptors, cryptochromes, in the reef-building coral Acropora millepora. In addition to being cryptochrome genes from one of the earliest-diverging eumetazoan phyla, cry1 and cry2 were expressed preferentially in light. Consistent with potential roles in the synchronization of fundamentally important behaviors such as mass spawning, cry2 expression increased on full moon nights versus new moon nights. Our results demonstrate phylogenetically broad roles of these ancient circadian clock-related molecules in the animal kingdom.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Levy, O -- Appelbaum, L -- Leggat, W -- Gothlif, Y -- Hayward, D C -- Miller, D J -- Hoegh-Guldberg, O -- New York, N.Y. -- Science. 2007 Oct 19;318(5849):467-70.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Centre for Marine Studies, University of Queensland, St. Lucia 4072 QLD, Australia.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/17947585" target="_blank"〉PubMed〈/a〉

    Complex diel cycles of gene expression in coral-algal symbiosis (2011)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2011-01-15
    Description: Circadian regulation of plant-animal endosymbioses is complicated by a diversity of internal and external cues. Here, we show that stress-related genes in corals are coupled to the circadian clock, anticipating major changes in the intracellular milieu. In this regard, numerous chaperones are "hard-wired" to the clock, effectively preparing the coral for the consequences of oxidative protein damage imposed by symbiont photosynthesis (when O(2) 〉 250% saturation), including synexpression of antioxidant genes being light-gated. Conversely, central metabolism appears to be regulated by the hypoxia-inducible factor system in coral. These results reveal the complexity of endosymbiosis as well as the plasticity regulation downstream of the circadian clock.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Levy, O -- Kaniewska, P -- Alon, S -- Eisenberg, E -- Karako-Lampert, S -- Bay, L K -- Reef, R -- Rodriguez-Lanetty, M -- Miller, D J -- Hoegh-Guldberg, O -- New York, N.Y. -- Science. 2011 Jan 14;331(6014):175. doi: 10.1126/science.1196419.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Mina and Everard Goodman Faculty of Life Sciences, Bar-Ilan University, Ramat-Gan 52900, Israel.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/21233378" target="_blank"〉PubMed〈/a〉

    Electro-optical phase shift in polymer dispersed liquid crystals (2000)
    Springer

    Notes: Abstract: An anisotropic version of the Maxwell Garnett approximation is applied for studying the electro-optical phase modulation by polymer dispersed liquid crystals (PDLC). The PDLC contain bipolar liquid crystal droplets that can be reoriented by an external field causing a change in the optical birefringence. This approach provides an explicit link between the droplet orientation distribution and the electro-optical phase shift. For aligned droplets we find that the sharpness of the change in the birefringence may be controlled by selecting the initial orientation. For a planar distribution we find sharp transitions with a hysteresis loop whose width depends on the droplet concentration. For a random distribution, the droplet orientation and the optical phase shift change more gradually with the applied field. These results demonstrate that PDLC may be suitable for a wide range of electro-optic applications based on their field-induced phase modulation properties. In addition, it is apparent that the optical phase shift is quite sensitive to changes in droplet orientation. It should therefore be useful for studying reorientation phenomena in PDLC, overcoming the problems due to light scattering in these materials.
